Fire Proofing

Ummm...... when you don't want a fire?

good sense of humour but sound is still coming. Anyway my question is, which one is better:- kmass (paint) or darchem (sheet/cover)

Only when it's required; otherwise, it's a waste of money.

When there's a serious process materials containment problem brought on by lack of maintenance and can't-be-bothered-itis?

Assuming there are local codes covering this application, then you would follow local codes.

Credit-to-all-previous-replies (esp. fixitorelse), and add:

Does common sense not dictate that certain parameters such as WHAT IT IS that you're needing to protect, and HOW HEAVY YOUR WALLET IS might come into play, in the equation...?

Really: "Can somebody please tell when to use paint like k-mass and jacket like darchem or bilco for fireproofing." Where is the question-mark (?)

Try studying a bit ... at LEAST enough to understand the vernacular of the topic you wish to address, in question fashion.

Generally-speaking, paints are for cosmetic purposes; protective coatings are used to prevent corrosion; linings protect articles in immersion service(s); intumescent coatings are generally used for "fire-proofing" (they don't "fireproof", but they reduce harm that would be inflicted by fire..."passive fire protection"). <_{see both links}>

Wishing you luck in your studies.
